SR EN 13757-5:2009

This standard defines the requirements for the protocols to use when performing relaying in wireless meter readout networks. This document is an extension to Part 4 of EN 13757, Wireless meter readout (Radio meter reading for operation in the 868 MHz to 870 MHz SRD band). It supports the routing of mode R2, but the routing of mode S and T is not supported. Additional parts of this standard are: EN 13757, part 1: Data exchange EN 13757, part 2: Physical and link layer EN 13757, part 3: Dedicated application layer EN 13757, part 4: Wireless meter readout (Radio meter reading for operation in the 868 MHz to 870 MHz SRD band) EN 13757, part 6: Local Bus The main use of this standard is to support routed wireless networks for the readout of meters. NOTE Electricity meters are not covered by this standard, as the standardisation of remote readout of electricity meters is a task for IEC/CENELEC.
